Amino sugars reflect microbial residues as affected by clay mineral composition of artificial soils
GJ Pronk, K Heister, I Kögel-Knabner - Organic Geochemistry, 2015 - Elsevier
Microbial residues are important contributors to soil organic matter (SOM). However, the
effect of mineral composition on microbial activity and thereby SOM development is not well
understood. Here, we used artificial soils composed of four different mixtures containing
illite, montmorillonite, ferrihydrite and charcoal to study the effect of mineral composition on
SOM development. In addition, silt-and sand-sized quartz were used to provide texture,
sterilised manure was added as OM source and the mixtures were inoculated with a …
